오라클 클라우드로 하고 있고 포트 개방은 80, 443, 8080, 8000, 9000, 3306 해주었습니다.

도커 포테이너 - 서비스에서 django_container_gunicorn이 이상한거 같습니다.

이건  django_container_gunicorn 로그입니다.

안녕하세요!
질문 확인했습니다.

일단 저도 처음 보는 에러네요.
확실히 gunicorn쪽에 문제가 있는 것이 맞아보입니다.

gunicorn쪽에 문제가 있으니
nginx단에서도 서버를 연결하는 데에 문제가 있는 듯 하구요.

그래서 첨부해주신 깃 저장소를 확인해보니,
Dockerfile 에서 조금 이상한 점을 확인했습니다.

마지막 CMD 를 통해 커맨드를 명시해주는 부분에서

CMD [ ... 중략 ... --bind 0.0.0.0/8000"]

이 조금 의심이 됩니다.
저희 강좌에서는 이 부분이

CMD [ ... 중략 ... --bind 0.0.0.0:8000"]

로 / 가 아닌 : 로 설정되어 있습니다.

"/" 와 같은 표기는 보통 IP 허용 영역을 지정하는,
CIDR 표기법에 사용되는 기호입니다.

저희는 포트 번호를 지정하는 것이 목적이기에,
한번 : 으로 해당 내용을 수정하신 후,
이미지를 다시 빌드하고 구동해보시길 바랍니다.


그럼에도 문제가 생기거나,
답변이 부족한 부분이 있다면 계속 질문 남겨주시길 바랍니다.

좋은하루 보내세요!
감사합니다-
